This Kensington Natural Look CatchMask™ Fly Mask with Nose and Ears functions as a fly mask until you attach a lead rope snap through the latch assembly, converting the mask to a secure catch-halter. Unlike most other fly masks, the CatchMask™ was designed to look natural to other horses, therefore stable mates with a habit of removing each other's masks tend not to. The long nose combined with the ear coverings provide the utmost portection against pesky bugs.
